In vivo evidence supports the effectiveness of the longevity-associated protein LAV-BPIFB4 in reducing adipose tissue-derived mediators of systemic inflammation to prevent vascular insult and atheromatous change.

ABSTRACT: Obesity triggers chronic low-grade inflammation contributing to cardiovascular and metabolic diseases. Over-release of adipokines and pro-inflammatory mediators by white adipose tissue (WAT) enhances inflammation through a feedforward loop involving endothelial and immune cells, promoting atherosclerosis. Our previous studies showed that in vivo gene transfer of the longevity-associated variant (LAV) of BPIFB4 restores endothelial and cardiac function and reduces systemic inflammation in mouse models. Here we investigated the anti-inflammatory potential of orally administered recombinant rhLAV-BPIFB4 in ApoE-/- mice fed a high-fat diet to elucidate its role in modulating endothelial dysfunction primed by adipose tissue inflammation. We studied n = 5 ApoE-/- mice on standard diet (SD
